The University will appoint 3 partnering contractors under a framework arrangement based on a JCT 2011 form of contract, on a design and build basis, to procure works across all campuses of its estate for a period of 4 years from June 2012, with an estimated total value (over the 4 year duration of the framework) of between 5 000 000 and 20 000 000 GBP. These figures cannot in any circumstances be guaranteed and nor should they be taken as a minimum or maximum amount. These figures are an estimate based on a previous framework agreement but no guarantee can be made that expenditure under the Framework which is the subject of this procurement process will reach 5 000 000 or that it will not exceed 20 000 000. The University's role will be that of client and employer of the contractors requiring the contactors to carry out such works and/or services as the University requires at its campuses and to the University's building stock, whether that be new construction work, refurbishment; renovation, alteration and extension to the building stock.
